Recently, Dan Olson, a mechanical engineering student at the University of Michigan, released a micrometer design that can be 3D printed , which has caused many 3D printing enthusiasts to respond positively. Micrometers, also known as spiral micrometers, are tools that use precision threads to measure very small distances or thicknesses and are used in mechanical engineering, machining, and other machinery industries. Although the desktop 3D printer is not known for its accuracy, Dan Olson has figured out how to do it quite well—especially considering that it is only the first version, and Olson admits that he did not spend enough time to properly align the screws. Therefore, this 3D printed 2.5-inch micrometer has a slight deviation, although its minimum scale is 5 inches per thousand, but the shortest object that can be measured is about 12 thousandths of an inch, with an error of +/- 3/1000. Between inches. Although it is more of a toy, it may never be used in real-world mechanical engineering scenes. But as a precision measurement tool for the first 3D printing, it is still quite impressive. “The basic components of this micrometer are 6.7 inches tall, so make sure your 3D printer has enough space. I use a 10% fill rate and a .15 mm layer height, and print two parts at the same time, it takes 18 hours. The 3D printing is done, and about 200 grams of wire is used. Because the material is hard, it will be very hard to screw it up, but it will be a few more times," Olson said. Earlier this week, Olson uploaded the microscopic 3D printed file to the Internet and received a lot of feedback from 3D printing enthusiasts. Olson has now modified some of these designs. "I re-uploaded the design of the pole because it's too deep and it's too painful to turn. But it's just a small change, so you probably don't need to download it again," he wrote. It is understood that Olson has indicated that as long as time permits, he will continue to design a smaller version of the micrometer, and a metric version of the micrometer.
